unt of a journeyman saddler； twenty…three years of age； of rather robust constitution； whose hands exhaled a smell of sulphur so powerful and penetrating as to rapidly fill any room in which he happened to be。 Rayer was once consulted by a valet…de…chambre who could never keep a place in consequence of the odor he left behind him in the rooms in which he worked。
Hammond is quoted with saying that when the blessed Venturni of Bergamons officiated at the altar people struggled to come near him in order to enjoy the odor he exhaled。 It was said that St。 Francis de Paul； after he had subjected himself to frequent disciplinary inflictions； including a fast of thirty…eight to forty days； exhaled a most sensible and delicious odor。 Hammond attributes the peculiar odors of the saints of earlier days to neglect of washing and； in a measure； to affections of the nervous system。 It may be added that these odors were augmented by aromatics； incense； etc。； artificially applied。 In more modern times Malherbe and Haller were said to diffuse from their bodies the agreeable odor of musk。 These 〃human flowers；〃 to use Goethe's expression； are more highly perfumed in Southern latitudes。
Modifying Causes。According to Brieude； sex； age； climate； habits； ailments； the passions； the emotions； and the occupations modify the difference in the humors exhaled； resulting in necessarily different odors。 Nursing infants have a peculiar sourish smell； caused by the butyric acid of the milk； while bottle…fed children smell like strong butter。 After being weaned the odors of the babies become less decided。 Boys when they reach puberty exhibit peculiar odors which are similar to those of animals when in heat。 These odors are leading symptoms of what Borden calls 〃seminal fever〃 and are more strongly marked in those of a voluptuous nature。 They are said to be caused by the absorption of spermatic fluid into the circulation and its subsequent elimination by the skin。 This peculiar circumstance； however； is not seen in girls； in whom menstruation is sometimes to be distinguished by an odor somewhat similar to that of leather。 Old age produces an odor similar to that of dry leaves； and there have been persons who declared that they could tell approximately the age of individuals by the sense of smell。
Certain tribes and races of people have characteristic odors。 Negroes have a rank ammoniacal odor； unmitigated by cleanliness； according to Pruner…Bey it is due to a volatile oil set free by the sebaceous follicles。 The Esquimaux and Greenlanders have the odors of their greasy and oily foods； and it is said that the Cossacks； who live much with their horses； and who are principally vegetarians； will leave the atmosphere charged with odors several hours after their passage in numbers through a neighborhood。 The lower race of Chinamen are distinguished by a peculiar musty odor； which may be noticed in the laundry shops of this country。 Some people； such as the low grade of Indians； have odors； not distinctive； and solely due to the filth of their persons。 Food and drink； as have been mentioned； markedly influence the odor of an individual； and those perpetually addicted to a special diet or drink have a particular odor。
Odor after Coitus。Preismann in 1877 makes the statement that for six hours after coitus there is a peculiar odor noticeable in the breath； owing to a peculiar secretion of the buccal glands。 He says that this odor is most perceptible in men of about thirty…five； and can be discerned at a distance of from four to six feet。 He also adds that this fact would be of great medicolegal value in the early arrest of those charged with rape。 In this connection the analogy of the breath immediately after coitus to the odor of chloroform has been mentioned。 The same article states that after coitus naturally foul breath becomes sweet。
The emotions are said to have a decided influence on the odor of an individual。 Gambrini； quoted by Monin； mentions a young man； unfortunate in love and violently jealous； whose whole body exhaled a sickening； pernicious； and fetid odor。 Orteschi met a young lady who； without any possibility of fraud； exhaled the strong odor of vanilla from the commissures of her fingers。
Rayer speaks of a woman under his care at the Hopital de la Charite affected with chronic peritonitis； who some time before her death exhaled a very decided odor of musk。 The smell had been noticed several days； but was thought to be due to a bag of musk put purposely into the bed to overpower other bad smells。 The woman； however； gave full assurance that she had no kind of perfume about her and that her clothes had been frequently changed。 The odor of musk in this case was very perceptible on the arms and other portions of the body； but did not become more powerful by friction。 After continuing for about eight days it grew fainter and nearly vanished before the patient's death。 Speranza relates a similar case。
Complexion。Pare states that persons of red hair and freckled complexion have a noxious exhalation； the odor of prussic acid is said to come from dark individuals； while blondes exhale a secretion resembling musk。 Fat persons frequently have an oleaginous smell。
The disorders of the nervous system are said to be associated with peculiar odors。 Fevre says the odor of the sweat of lunatics resembles that of yellow deer or mice； and Knight remarks that the absence of this symptom would enable him to tell whether insanity was feigned or not。 Burrows declares that in the absence of further evidence he would not hesitate to pronounce a person insane if he could perceive certain associate odors。 Sir William Gull and others are credited with asserting that they could detect syphilis by smell。 Weir Mitchell has observed that in lesions of nerves the corresponding cutaneous area exhaled the odor of stagnant water。 Hammond refers to three cases under his notice in which specific odors were the results of affections of the nervous system。 One of these cases was a young woman of hysterical tendencies who exhaled the odor of violets； which pervaded her apartments。 This odor was given off the left half of the chest only and could be obtained concentrated by collecting the perspiration on a handkerchief； heating it with four ounces of spirit； and distilling the remaining mixture。 The administration of the salicylate of soda modified in degree this violaceous odor。 Hammond also speaks of a young lady subject to chorea whose insensible perspiration had an odor of pineapples； a hypochondriac gentleman under his care smelled of violets。 In this connection he mentions a young woman who； when suffering from intense sick headache； exhaled an odor resembling that of Limburger cheese。
Barbier met a case of disordered innervation in a captain of infantry； the upper half of whose body was subject to such offensive perspiration that despite all treatment he had to finally resign his commission。
In lethargy and catalepsy the perspiration very often has a cadaverous odor； which has probably occasionally led to a mistaken diagnosis of death。 Schaper and de Meara speak of persons having a cadaveric odor during their entire life。
